I'd like to verify if the following is RAW. It's very pivotal to a game of mine.
An Illusionist wizard will cast Mirage Arcane, keeping the illusion of the area to be exactly the same as the area now. This conceals the presence of the illusion.
Fly over to the targets.
When they're in sight, use Malleable Illusions. All but one target will be surrounded by a single Adamantine dome that doesn't touch them, but it does separate everyone but one. Follow up with Illusory Reality, trapping everyone inside the dome in pitch darkness.
- Each Adamantine panel will have AC 23, HP 27 per inch of thickness. But there's nothing stopping the panel from being 10 inches thick, so the actual wall will have 270 HP.
Engage in a one on one fight with the target, win
Rinse and repeat
Alternatively, step #3 could have no Illusory Reality section, as Mirage Arcane is tactile anyway. It justifies the solidity (having AC and HP) of the dome wall more with that power used, though.
